# Are complex varieties Kahler? - Algebraic, non-projective complex manifolds

Let $X/\mathbb{C}$ a nonsingular proper variety and $X_{an}$ it's associated analytic space. Is $X_{an}$ necessarily Kahler? Certainly we know this if $X$ is projective.

A complex torus is algebraic iff it is projective. Are there Kahler manifolds which are algebraic, but not projective?

Any abstract algebraic compact complex manifold is Moishezon. By Moishezon's theorem, any Kähler Moishezon manifold is projective algebraic. There are non-projective proper complex varieties, so $X_{an}$ is not necessarily Kähler. This is represented in the diagram at the end of Hartshorne's Algebraic Geometry Appendix B.
